pijul/*: reorganize imports and remove extern crate

I personally find it easier to mentally parse imports when they are separated into blocks of std imports, external crate imports, and internal crate imports.

Additionally, #[macro_use] extern crate is a Rust 2015-ism, and can be replaced by useing the macro (derive or procedural).
